what is meant by interrupt vector table? what it's use?
Answer Posted / md. fajlul karim
Interrupt vector table contains the addresses of the all
different types of interrupts. it generally occupies the
first 1k addressable memory of the system. Generally the
interrupt vector is a 4 byte value occupying 256 rows of 4
byte memory.
When the CPU receives an interrupt , the current execution
is stopped and the next instruction address is pushed to
stack and the program counter jumps to the interrupt vector
table to the corresponding address, and after completion of
the handling of interrupt, the main program is resumed by
poping the previously pushed addressed and continued.
